CCGT 09T301 AH725 rhombic indexable insert for turning — Tungaloy, PVD-coated, 0.1 mm radius

The CCGT09T301 AH725 is an ISO-standard rhombic indexable insert engineered for external and internal turning, offering a universal, fracture-resistant PVD-coated carbide grade optimised for steel and stainless steel applications.

• ISO rhombic 80° shape for stable cut
• PVD-coated carbide AH725 for long life
• 0.1 mm corner radius for fine profiling
• Cylindrical hole with 40°–60° countersink
• Single-sided chipbreaker for consistent chips

Increased process reliability and sustained productivity

The combination of a PVD-coated carbide grade and a fracture-resistant specification provides a clear process advantage: improved tool life and stable cutting when materials vary. The AH725 grade is formulated for consistent performance across both steel and stainless steel, reducing unexpected insert failure and interruptions. PVD (physical vapour deposition) creates a thin, wear-resistant layer that lowers flank wear and helps maintain cutting-edge geometry, which in turn supports predictable machining cycles and fewer tool changes.

Precision geometry for improved surface finish and repeatability

A defined 80° rhombic geometry together with a 0.1 mm corner radius and a 7° relief angle results in reliable contact conditions and a controlled cutting zone. The modest corner radius allows for fine profiling and modest radii in turned contours while keeping radial cutting forces manageable; this reduces the need for rework and helps to achieve target tolerances more quickly. The insert thickness of 3.97 mm contributes to stiffness at the clamping point, promoting repeatable surface finish and dimensional stability in serial production.

Seamless integration into ISO tool systems and straightforward handling

Designed as an ISO indexable component, the insert mates with standard external holders and boring bars when form, relief angle, tolerance class, fastening, size and thickness are matched. The cylindrical hole with a one-sided countersink (40°–60°) ensures secure clamping and correct seating in most ISO-compatible toolholders. The single-sided chipbreaker assists in forming predictable chips on interrupted and continuous cuts alike, simplifying chip evacuation and lowering the risk of built-up edge. For workshops seeking dependable replacement parts, the clear ISO designation supports fast identification and inventory management.

FAQ

What materials is this insert suitable for?
The CCGT09T301 AH725 Tungaloy indexable insert is specified for machining steel and stainless steel, with the AH725 grade offering universal, fracture-resistant behaviour across varying alloys.

How does the PVD coating benefit cutting performance?
A PVD-coated carbide substrate reduces flank wear and improves heat resistance; the coating on the AH725 grade helps preserve cutting geometry and extends tool life under mixed-material or demanding turning conditions.

Which insert geometry affects holder compatibility?
Compatibility depends on the insert form, relief angle (7°), tolerance class, fastening method, size (09) and thickness (3.97 mm); the 80° rhombic profile and the cylindrical hole with countersink require matching ISO toolholders.

What chip control can be expected with this plate?
The single-sided chipbreaker offers consistent chip formation for both continuous and interrupted cuts, improving evacuation and lowering the risk of built-up edge when turning steels with stable cutting parameters.
